	Takes a PID, a Process handle, an u32, an u64 pid_reserved, returns an output [[#IUserSession_2\|IUserSession]].		Takes a PID, a Process handle, an u32, an u64 pid_reserved, returns an output [[#IUserSession_2\|IUserSession]].

			Official sw uses hard-coded value 0x1 for the u32.

			An error is returned when there's already an [[#IUserSession\|IUserSession]] open with the same PID.

			The output is determined using the flag updated by [[#Start\|Start]]/[[#Stop\|Stop]].

			=== RequestUpdate ===
			Takes two type-0x6 output buffers and a type-0x5 input buffer.

			=== Start ===
			No input/output.

			Besides logging, this calls a func which essentially clears a state field and sets a flag, and also calls a func.

			The thread which handles generating/sending ADSP commands will only do so when the above flag indicates the state is Started.

			=== Stop ===
			No input/output.

			After logging, this calls a func which essentially returns when the flag from [[#Start\|Start]] is not set. Various funcs are called, then the flag is cleared. If needed, this waits on an event, then this returns.

			=== QuerySystemEvent ===
			No input, returns an output Event handle.
